SPECIFICATION forming* part of Letters Patent No. 723,181, dated March17, Application filed November. 11, 1902. Serial No. 130,866. .(Nomodel.)

To all whom t may concern,.- Be it known that we, CHARLES W. RAY-1 MOND,residing at Dayton, inthe county of.` VMontgomery and State of Ohio, andDAVIS.A BROWN, residing at Chicago, in the county of Cook and State ofIllinois, citizens of the' fUnited States, have inventedcertain new anduseful Improvements in Brick-Cutting-Ma-` chines; and we do herebydeclare the follow-f ing to be a full, clear, and exact description.

of the. invention, such as will enable' others skilled in the art towhich it appertains to make and use the same,reference being had totheaccompanying drawings, and to the` letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in brick-cutting machines.

The object of the invention is to produce; a machine with agreatly-increased capacityfor cutting bricks. E

Theinvention comprises a cutting-reel hav-A ing horizontal'and rotarymovements and adapted to cnt a series of bricks fromA acontinuously-moving clay column or bar. The` horizontal movement, during`which the series of brick are cut,\is given said cutting;` reel by themoving clay bar. The rotary; movement is imparted to said reel bysuitable, power, which also reverses the horizontal movement of saidreel after each cutting operation and resets saidreel for the next suc'-ceeding operation.

The invention also comprises governing; mechanism controlled by theforce of the mov-l ing clay bar and by means of which the speeds of thecutting-reel and the moving clay bar are maintained inoperative'relation, so thatV any danger of severing or breakingthecontinuously` advancing clay bar is obviated and the machine is enabledto operate successfully. An 'automatic brake is ,operatedl through saidgoverning mechanism for checking the power for #rotating and resettingthe1 cutting-reel when the speed assumes an in` ,operative relation withthe speed of the movting clay bar, and the invention comprisesother-featuresand details hereinafter de-1 scribedand claimed.

In a detail description of the invention similar reference charactersindicate corresponding parts. l

"A designates the nozzle end of a well-known brick-machine, from which abody of clay is forced by means of a screw or auger (not shown) in acontinuous bar l onto the feedtable b and thence to the cutting-reel J.The feed-table is'constructed as follows:

\ C and` O are upper and lower I-beams `which Iare connected to fourupright standards D.

E designatesa series of rollers which are journaled in frames F, securedto the upper `I-beams O.

AGr' and G are pulleys Which are journaled in bearings H and H' on twoof thestandards D and over which am continuous belt G passes, said beltpassing over Nthe series of rollers E. The bar of clay I enters tliebelt G at said pulley G and advances to the cutting-reel J, where aseries of bricks K. are cut and delivered to an off-carrier L at thedelivery end Z of the machine.

The cutting-reel consists of two open sidel frames M M, having lateralflanges f", be-

IOO

tween which are supported two ring-gears M' M'. These frames are tiedtogether by an upper bar M" and two lower bars or castings M3. Theplaten upon which the clay bar I moves lies between the two side platesM M and consists of a horizontal portion made up of a series of sectionsP", (shown more clearly in Fig. 8,) which have a series of interveningspaces a and a series of rear vvertical walls P3, which join the bottomor horizontal portions P". The rear walls P3 are integral parts of aseries of hangers or depending arms P', which are rigidly clamped to ahorizontal shaft P, that lies between the centers of the frames M M andis fixed to the hubs P4 thereof. The bottom sections P of the platen arebolt-ed to the arms P', as shown in Fig. 9. The sections forming saidplaten are of uniform size, and each is substantially the size of thebrick' required. The openings a between each of said plates or sectionsare provided for the passage of the wire cutters b, of which there isone in each set of wires in excess of the number of bricks that are cutupon the platen. The number of such Wire cutters b depend upon the sizeof the brick to be cut, as do also the number of the sections of theplaten. The said wire cutters b are in two sets, placed in diametricallyopposite positions. The wires of each set are fastened near the centerof the reel by a series of clamps c, which are fixed to the shaft P androtate therewith in the movement of the reel. The outer ends of saidwire cutters are fastened to a series of hooks d, that are passedthrough openings in supports d', hinged at d" to brackets (Z3, which areconnected t0 bars f, said bars being connected at each end f' Io thering-gears M'. hooks d are held by a series ofspiral springs e. (SeeFigs. l0 and ll.) The ring-gears M' M turn and are supported uponrollers d, which run on the lower [ianges f" of the side frames M. (SeeFig. 7.) The rollers d4 areinclosed at their outer ends -by the fiangesd3 of the ring-gears and are supported on pins which are fixed in ringsd3, which lie between the flanges of the side frames M.

The above-d escribed mechanism comprises, as before stated, thecutting-reel, which is given a continuous rotary motion through pinionsQ, 'that mesh with the ring-gears. The pinions Q are on a shaft which ismounted in the frames M M and are driven by a gear Q' on shaft Q", alsomounted in said frames. The shaft Q" is connected to a shaft H3 by aflexible coupling Q3, which permits the reel to have horizontalmovement. The reel is supported andis movable on rollers N, which arefast ou shafts N', that are loose in the lower tie-bars M3, saidtie-bars having slots n, in which the ends of said shafts lie. 'lherollers N run on slightly-inclined V- shaped tracks which are secured tothe lower I-beam C. As the cutting-reel moves away from the feed-table Bon said slightly-inclining tracks O the gap formed by said move- Thevment between the feed-table and the reel is filled or occupied by a pairof lazy-tongs R, which support two rollers EX on a plane with therollers E and receive the clay bar I as said bars move o the belt G. Thelazy-tongs referred to provide a support for the clay bar to enter thereel and permits the reel to have the necessary horizontal movement fromand toward the feed-table. The lazy-tongs on each side are secured atone end to arms g, fastened to the upper I-beams C', and the other endsof said lazy-tongs are fastened to an oil-pan g', which is fixed to theadjacent reel-frame M. The oil-pan g' supports two horizontal rollersg", which oil the bottom of the clay bar I to permit it to easily passonto the platen, and the said oil-pan also contains two vertical rollersg3, which oil the opposite sides of the clay bar in passing into thereel.

The rotating belt Gis kept clean by a scraper h, fastened to a castingh', secured to adjacent standard D.

S designates the main power-shaft, through which power is conveyed toimpart the rotary and resetting movements of the reel. This shaft isconnected to a shaft S' by a universal coupling S", shaft S' beingsupported in bearings S3, fastened to the lower I-bearn C on one side ofthe machine. From shaft S' power is transmitted to a cross-shaft Tthrough bevelgears T', said shaft T being supported in bearings T". Thisshaft T has fixed to it a pulley T3. The power introduced to the pulleyT3 is transmitted through the governing devices to the shaft H3, fromwhich the cutting-reel receives its continuous rotary motion, and fromshaft H3 to shaft I", through which the .resetting movement is impartedto said reel.

The governing mechanism through which the power is regulated is shown inFigs. 6, 6, and 63 and consists of the following mechanism: A' is abevel-gear keyed to a shaft A",

upon which is clamped the pulley G'. As the clay bar I moves forward onbelt G over and onto the pulley G said gear A' is rotated and meshingwith bevel-pinion A3, which is keyed to a sleeve B', rotates saidbevel-pinion. The sleeve B' turns loosely in a box B", through which theshaft B3 passes, said box B" being fastened to a standard D. On theexposed end of the sleeve B' is a disk C3, which has four lugs t,arranged at opposite points.. Between each two of said lugs t is placedthe ball end t' of two bell-crank levers 15", the fulcrums of which areon a sleeve t3, keyed to the shaft B3. On the other arm of saidbellcrank levers are fastened links s, said links being also fixed to asleeve s'. The sleeve s' has an annular groove t', in which rollers c"run, said rollers being supported on pins t", fixed to a swinging armt3. (See Figs. 6,6", and 12.) The arm 013 is pivoted to a pin 4, whichis fixed to one of the I-beams C'. To the lower end of said arm 3 isconnected an arm t3, 'the other end of which Vis attached to an arm i,which is connected to a shaft i7.

IIO

V gears H", H5, H5, and H7.

'This latter shaft has a rocking movement on (See Fig. 3,.) To shaft 7there bearing is. is keyed an arm t9, one end of which supports theflanged idler D', over which a loose belt D3 passes, said belt alsopassing over pulleys Ts and D". To the other end of the arm 9 issecuredl an adjustable weight D4 to balance the idler D'. To the shaft1'7- is further keyed an arm E5, to one end'of which is swung an arm E',that has attached to it a friction-brake E". This brake is connected toan arm E4, fastened to oneef the upper I-beams 0'; To shaft F" is keyeda spurpinion H", meshing with a spur-gear I-IS on shaft H4. To the otherend of shaft H4 is keyed a bevel-pinion H5, meshing with bevelgear H5,the latter gear being keyed to shaft B5. Pinion H5 also meshes with abevel-gear H7, keyed to shaft H8, said shaft being connected to theflexible coupling Q3, which unites the shafts HS and Q", the lattershaft, as before stated, driving the reelg gearing. (See Fig. 5.) Onshaft H8 is also keyed a bevel-pinion H9, meshing with bevel-gear I',keyed to shaft I". On'this shaft I" is also keyed a cam I3, whichimparts to the cuttingreel its reversed or resetting movement. This camI5 works against a roller I4, turning on a pin secured in housingI6,supported on shaft I". The housing is fastened to the adjacent sideframe M by arm 17. (See Fig. l.) The shaft T carries a sprocket-wheelJ', over whichruns a chain belt J", that passes over alargersprocket-wheel J3, driving theoff- 1 carrier L.

Having described the invention, we will now proceed to outline theoperation thereof. The power coming intothe machine through and fromthere transmitted to shaft H8 through From shaft Hs it is transmittedtocam I3 on shaft I". The

i "i power thus introduced is regulated in its lltransmission to shaftH8 by the force or power G" the gear A' generated by the moving clay barI. The

clay bar moving forwardly engages the belt G, which is moved forwardtherewith at the same speed.` As said belt runs on pulleys G' and isalso rotated and in turn` drives the pinion A5, and thereby causes thesleeve C3 to turn on the shaft B5. l As the sleeve C3 rotates it movesthe bell-crank leverst" of the governing devices, and sleeve s' islikewise .moved forward through links s s on the shaft B3. As the saidsleeve moves forward the idler D' is raised through connections t5 and5to tighten the loose belt D5,

thereby causingthe power to be transmitted` from pulley T3 to pulley D".As pulley D" moves the mechanism of the entire table is started. 4Assuming the .cutting-reel to be reset,or in that position closest tothe feed-table, the advancing claybarI entering the platen P" will movethereel horizontally in the direction in which said clay baris moving.While the reel isthusbeing moved, it is also being rotated by thegearing Q and Q', which are bar transmits the horizontal movementto thereel. Therefore in the first or initial cut of the reel a full series ofbricks are not cut;

Abut in each succeeding operation the length of the platen is occupiedeach time by the clay bar and a full series of bricks are cut. As soonas the first set of wires b coming into operation has cut through theclay bar the reel is given its reversed horizontal or resetting movementby the cam I3 engaging the roller I4. During this resetting movement ofthe reel the clay bar in its continuous movement advances onto theplaten P", and when the said vreel has reached the limit ofits resettingmovement the said clay bar has moved entirely across the platen, and thereel is.` moved thereby to its outer horizontal position. The reel, asshown in Figs. l, 2, and 3, is at the limit of such outer horizontalposition. This will be readily apparent from the expanded position ofthe expanding and contracting support R. It will be borne in mind thatthe clay bar I in filling the platen P for each succeeding operation isnot required to move the full length of the platen. The reel moving inthe opposite direction in its resetting movement compensates forapproximately one-half the length of said platen, so that when said reelhas reached the limit of its resetting movement under the cam I5 theclay bar occupies the full length of the platen, or approximately so.Two series of bricks are cut in one revolution of the cutting-reel, andit will be understood the reel is reset by the cam 13 for each series.In case the power should run faster than the clay bar I is moving, andthereby create a liability of the same being broken or divided by thebelt G, the shaft B3 at such time is turned more rapidly than the sleeveB'. The result is the governing devices are reversed. This draws thesleeve s' in a reversed direction, or that position shown in full lines,(see Fig. 6,) which throws the idler D' away from the loose belt E3 andat the same time throws forward the arm E8 and applies the brake E" tothe fly-wheel F', thus checking the speed of the machine. When there isan equilibrium established between the speed of the power coming intothe machine through shaft T and the speed of the moving clay bar I, thegoverning devices are idle.
